VPL 2.10.1 (not a regression, it did not work with previous version either) I want to use VPL to decode a H264 sequence embedded in MP4 container (link below to...

Using a 3 float channels TIFF with COMPRESSION_SGILOG is supported by a wide range of softwares However, I [thought that it was possible](http://www.anyhere.com/gward/pixformat/tiffluv.html) to use a single (Y) plane as...

Chunk preallocation outside of dataset resize

3

I use a chunked dataset for incremental I/O. When I need to append data, I enlarge the dataset. Chunks are automatically allocated as needed. For performance, since I approximately know...

### Feature description Currently, (gdal 3.8) the netCDF driver does not support AddBand(). This driver could have such a feature since bands can be NETCDF variables. ### Additional context quoted...

supports empty kernels in cuda::SeparableLinearFilters

1

[#25408](https://github.com/opencv/opencv/issues/25408) When only 1D convolution is needed (row or column filter only), `cuda::LinearFilter` might be slower than `cuda::SeparableLinearFilter` Using `cuda::SeparableLinearFilter` for 1D convolution can be done by using a `(1)`...

### Describe the feature and motivation Currently, `remap()` is applied as `dst(x, y)

cuda::remap() returns different results from cv::remap()
